Browning SHP1HUB Shaft Hub

The Browning SHP1 HUB is a three‑part shear‑pin hub assembly designed for a P1 bushing, built to protect drives from overloads or jams by releasing a necked pin at a predetermined torque. It features a bushed bore for a P1 bushing with a bore range of 1/2 in to 1-3/4 in and a through‑bore length of 2.125 in, plus a flange outside diameter of 7-5/8 in and an overall diameter of 7.625 in. The bolt pattern uses a 6.5 in bolt circle with 3 bolts (1/2 in diameter) and a 3/8 in pin outside diameter, delivering zero backlash and a maximum operating speed of 500 rpm. Crafted from steel and equipped with a lubrication fitting, the SHP1 HUB weighs about 10.2–10.4 lb. Torque characteristics include a minimum trip torque of 1,340 in-lb and a maximum torque capacity of 14,950 in-lb, making it suitable for conveyors and other power‑transmission applications that require a releasable, torque‑limited connection to prevent gear or shaft damage. Browning shear‑pin hubs are typically composed of steel sprockets, hub assembly, and a malleable bushing, and are designed to clamp to a shaft with a P1 bushing to provide reliable overload protection while maintaining precise alignment through the fixed bolt pattern. The SHP1 HUB is listed in Browning’s catalog as the appropriate shear‑pin hub for P1 bushings and carries the manufacturer’s part designation for ordering and service support.
